Updating data of a controller of a primary device of a power substation

Abstract

Exemplary embodiments for updating a controller of a primary device of a power substation. An actual time is received from a time server via a cell phone communication network with a mobile device and the actual time is sent with the mobile device via a local wireless communication network to the controller.

What is claimed is: 
     
       1. A method for updating a controller of a primary device of a power substation, the method comprising the steps:
 receiving an actual time (t g ) from a time server via a cell phone communication network with a mobile device; and 
 sending, with the mobile device, the actual time (t g ) via a local wireless communication network to the controller. 
 
     
     
       2. The method of  claim 1 , comprising the step of:
 synchronizing an internal clock of the controller with the actual time (t g ). 
 
     
     
       3. The method of  claim 1 , comprising the step of:
 storing the actual time (t g ) in the controller as clock update time (t up ) for later reference. 
 
     
     
       4. The method of  claim 2  comprising the step of:
 storing the actual time (t g ) in the controller as clock update time (t up ) for later reference. 
 
     
     
       5. The method of  claim 1 , comprising the step of:
 sending, with the mobile device, configuration parameters to the controller via the local communication network. 
 
     
     
       6. The method of  claim 2 , comprising the step of:
 sending, with the mobile device, configuration parameters to the controller via the local communication network. 
 
     
     
       7. The method of  claim 3 , comprising the step of:
 sending, with the mobile device, configuration parameters to the controller via the local communication network. 
 
     
     
       8. A method for updating data from a controller of a primary device of a power substation, the method comprising:
 receiving diagnostic data from the controller via a local wireless communication network, the diagnostic data having timestamps (t ts ) with respect to a local clock of the controller; 
 receiving a local clock time (t l ) via the local wireless communication network from the controller; 
 receiving an actual time (t g ) from a time server; and 
 recalibrating the timestamps (t ts ) of the diagnostic data with respect to the local clock time (tl) and the actual time (t g ). 
 
     
     
       9. The method of  claim 8 , wherein the local clock time (t l ) has been updated by:
 receiving an actual time (t g ) from a time server via a cell phone communication network with a mobile device; and 
 sending, with the mobile device, the actual time (t g ) via a local wireless communication network to the controller. 
 
     
     
       10. The method of  claim 8 , wherein the local clock time (t l ) has been updated by:
 receiving an actual time (t g ) from a time server via a cell phone communication network with a mobile device; 
 sending, with the mobile device, the actual time (t g ) via a local wireless communication network to the controller and synchronizing an internal clock of the controller with the actual time (t g ). 
 
     
     
       11. The method of  claim 8 , comprising the steps:
 calculating an time offset between the local clock time (t l ) and the actual time (t g ); 
 recalibrating the timestamps (t ts ) by changing a difference between a recalibrated timestamp time (t ts,r ) and a timestamp time (t ts ) proportional to a difference between the actual time (t g ) and the local clock time (t l ). 
 
     
     
       12. The method of  claim 9 , comprising the steps:
 calculating an time offset between the local clock time (t l ) and the actual time (t g ); 
 recalibrating the timestamps (t ts ) by changing a difference between a recalibrated timestamp time (t ts,r ) and a timestamp time (t ts ) proportional to a difference between the actual time (t g ) and the local clock time (t l ). 
 
     
     
       13. The method of one of  claim 8 , wherein the recalibrations is performed by the mobile device. 
     
     
       14. The method of  claim 8 , comprising the step of:
 sending the diagnostic data to a central system, wherein the recalibration is performed by the central system. 
 
     
     
       15. A mobile device, comprising:
 a first communication unit for communicating via a local wireless communication network; 
 a second communication unit for communicating via a cell phone communication network; 
 wherein the mobile device is configured to perform the method of updating a controller of a primary device of a power substation, the method comprising the steps: 
 receiving an actual time (t g ) from a time server via a cell phone communication network with a mobile device; and 
 sending, with the mobile device, the actual time (t g ) via a local wireless communication network to the controller. 
 
     
     
       16. A system, comprising:
 a controller for a primary device of a power substation; 
 a mobile device according to  claim 10 ; 
 wherein the controller has a communication unit for communicating via a local wireless network. 
 
     
     
       17. A non-transitory computer-readable medium, for storing a computer program for updating data of a controller of a primary device of a power substation, which, when the program is executed by a processor the processor is configured to execute the method of  claim 1 .
